To all whom t may concern: v l

Bev it known that we, CHARLES) DRADEm a subject of the King of Great Britain, and RAPHAEL ROGERS CANDEE, a citizen ofthe United States, both residing at Bakersfield, in the county of KernandState of California, have invented a new and useful Non- Leak Anchor Means for Supporting Liner- Pump Viorking Barrels, of which the following is a specification. Y

rlhis invention relatesl to the class of inventions set forth in our application for LettersPatent of the United States for nonleak seat and anchor for linerfpumpa'Serial No. 806,631, filed December 13, 191,3, patented August 31 1915, No. 1,151,765 in which we have shown a combination seat and anchor for liner pumps comprising a female member, a male member having an annular groove in its outer face and a ring of ductile metal provided in said groove; said ring being adapted to spread into frictional contact with said female member when said male member is forced into said female member, thus to form a non-leak seat.

An object of this invention is -to provide a manufactured article that is adaptable for application in the field with maximum ease and convenience. y

This invention includes a ductile metal ring adapted to fit on an insertible memberto be pressed into an extension seat adapted to receive said insertible member, said ring having an uneven external face so that outer portions of said ring upon forcible contact with the exterior seat, as the pump is forced down into place, will be successively swaged and made to flow upon other portions of the ring, thus to readily conform to, and to fit tightly in, the seat; and adapted to be condensed into and to fill, the space between the seat and the insertible member. Y

A further object is to provide aflexible or adjustable support for the pump barrel whereby said barrel will be allowed to accommodate itself to the plunger of the pump so as to avoid any binding or undue friction arising from disalinement.

The invention also comprises the combination with airing of the character described f a member having a collar or annular projection, and adjacent to such collar, a neck; and below such neck a reduced threaded portion; and a collar to screw onto the threaded portion to retain the joint-forming ring between Said shoulder and Cenar, than Said ring may be positively connected by the collar to a pump barrel or other hollow body to close the joint above said. hollow body to prevent leakage or accidental jarring loose during the operation of the pump'.

It also includes'the" combination herein- :after morepart'icularly pointed outv whereby it is made possible to conveniently install the workingk barrel with a' non-leak anchor-l -age withinthe pump tubing;l 1f" Y Other features of novelty mayl appear from the subjoined detail description.I f

The'accompanying drawings illustrate the invention.r f l,

Figure 1 is'a side elevation ofjanr anchor constructed in accordance with this invention and ready for attachment to the top of a working barrel of a deep well, and for insertion into an anchor seat in pump tubing. Fig. 2 is a bottoml view-of the lower end of said anchor.

Fig. 3 is a perspective sectional view of said anchor.

Fig. l is an axial section of the anchor attached to the working barrel, or workingl barrel extension," a. fragment :of which is shown being lowered ready to be- Inserted into its seat in pump tubing, a fragment `of whiclrtubing 1s shown. Fragments of a sucker rod and` working valve are also shown. l

Fig. 5 is an axial section analogous to Fig. 4l' showing the anchor fully seated in said seat.

Fig. 6 is an axial section of a construction of the anchor in which a plurality of anchor rings are used.

Fig. 7 is a perspective view of one of the anchor rings removed. -k Fig. 8 is a fragmental, axial section of a form of the invention having a special coupling and seat for pliable top anchor ring, and connected to the working barrel by a working barrel extension, the anchor rings being just in contact but not seated in their seats. l

Fig 9 is a broken elevation of the construction shown in Fig. 8 partly in section, the anchor rings being fully seated and' anchored. The foot valve of the pump is omitted in Figs. 8 and 9.

Fig. 10 is ay detached view half in elevation, half in section, of a'workin'g barrel and working barrel extension with anchor rings in place yready for insertion in the pump tubing', except that the sucker and suckerrod are omitted.

Fig. 11 is a broken View of a retainer detached.

Fragments of the sucker-rod and ball valve cage are shown installed in Figs. 11, 5, 8 andr9.

Like characters indicate like parts throughout the views and are distinguished by eX- ponents where various forms are indicated.

The collar 1 constituting a working barrel extension is interiorly threaded to receive the threaded end of a retainer 2 that is provided with an annular shoulder 3 and with a head 4 that can be turned by a wrench to screw and unscrew the retainer into and from the collar. The collar is provided with a ring seat L5 and, said ringseat may be formed by the end of the collar, as in Figs. 1 to 5, and in Fig. 8; or a distance from the end of thepcollar as shown at 5 in Figs. 6 and 10.

l/Vhen the parts are assembled there is between the ring seat 5 and the annular shoulder 3 a cylindrical neck a which may be formed on either or both the collar and retainer. Upon this neck there is mounted one or more rings 5 of ductile, condensible, compressible metal such as lead, Babbitt metal, copper, or the like, preferably filling the space between the shoulder and the seat. Said ring is internally cylindrical to iit the outside of the retainer 2 and is annularly grooved on the outside, and between and bounding the grooves 6 there are annular beads 7, said beads being of greater diameter than the collar 1, thus adapting the beads to contact with an internal circular taper anchor seat 8 through which the. collar 1 may freely pass; said seat being formed inside a hollow member 9 for connection with other parts of the pump.

Said beads are preferably half round and the construction of the ring is practically such that the annular halfl round beads 6 are, in effect, superposed upon a hollow cylindrical body, and are fixed apart fromeach other, being separated by said grooves; so that when said anchor is inserted into a circular anchor seat that is of less diameter than the beads, said beads will be swaged over into the grooves; each bead forming a non-leak anchoring member; a ring thus being formed with a plurality of ductile annuli that are condensable and swageable or capable of being made to flow under pressure to fill the space between the seat and the insertible member.

The anchor rings thus produced for the upper ends of the working barrels of liner pumps are made as separate articles of manufacture and may be kept in stock by the dealer and user; and all that is necessary in order to put the same to practical use is simply to apply the ring to the cylindrical neck provided therefor on either the collar 1 or on the retainer 2, or on both, as the case may be, and then the retainer is screwed home; whereupon the working barrel is retained by the retainer; and the parts may afterward be dis-assembled for application to the pump.

The bore of the retainer 2 is of less diameter than that of the working barrel and also than the diameter of the valve cage 12; and in assembling for use, the sucker rod 13 is inserted through the retainer 2 and screwed into the cage 12 on the end of plunger 14: before the retainer is screwed into its seat.

The plunger .'14 will be inserted through the collar or working barrel extension 1 and into theworking barrel 15 and into the liner 16 therein, and the threaded joints willY all be screwed home tight. f l

rlhe lower working barrely extension 17 has a non-leak anchor ring 18 which is described and claimed in our application for patent on appliance for forming a non-leak seat, filed April 17, 1915, SerialNo. 22,207.

By means of the upper working barrel extension 1, the support formedl by the nonleak seat for the working barrel is located at a distance above the working barrelso that more or less of flexible adjustment of the working barrel to the plunger will occur during the pumping operation, thus relieving the pump of friction that might otherwise occur.

When it is desired to pull the pump this is done by means of the sucker rod and its valve cage which engages the retainer 2 and may be made to jar and lift the pump from its seat.

When the working barrel has been pulled, the retainer may be unscrewed ind the anchor ring withdrawn and replaced with new for a repetition of the operation above described.

1n the form shown in Fig. 8 the hollow member in the form of a coupling 9 screwthreaded at its ends connects the pump tubing 10 and the pump barrel ll'and is provided with a taper anchor seat 8 between the screw-threaded ends to receive the beads of the non-leak anchor ring b.

In the form shown in Figs. 8 and 9 a ring seat 5 is formed on the end of the collar formed by a working barrel extension 1".

1n the form shown in Fig. 10 a ring seat 5 is shown formed below a neck a on the collar formed by working barrel eXtension 1X.

We claim 1. 1n an anchor for the working barrel of a liner pump, the combination with a collar secured to the working barrel and having a ring seat on its upper end, of a retainer detachably screwed into the collar and forming an externally cylindrical neck extendvso ing upwardly from the ring seat and having an annular shoulder above the neck, tubing for the working barrel, said tubing having an internal cylindrical tapered seat, a cylindrical ring of ductile metal on said neck and tting between the ring seat and the shoulder and having outer vannular beads and annular grooves, said annular beads being larger in diameter than said internal cylindrical tapered seat, so that when the working barrel goes down into position the beads fit themselves to said internal cylinn drical tapered seat.

2. In an anchor for the working barrel of a liner pump, the combination with a collar secured to the working barrel and having a ring seat on its upper end, of a retainer detachably screwed into the collar and forming an externally cylindrical neck extending upwardly from the ring seat and having an annular shoulder above the'neck, tubing for the working barrel, said tubing having an internal cylindrical seat, a cylindrical ring of ductile metal on said neck and tting between the ring seat and the shoulder and having outer annular beads and annular grooves, said annular beads being larger in diameter than said internal cylindrical seat, so that when the working barrel goes down into position the beads t themselves to said internal cylindrical seat.

3. rlhe combination with tubing, of a working barrel, a hollow member of less internal diameter than the tubing, a coupling connecting the tubing and the hollow member, said hollow member having an internal seat of less diameter than the tubing and greater diameter than the working barrel, a detachable tubular extension of the working barrel connected to the upper end of the'working barrel, a tubular retainer screwed into the extension and provided with a shoulder and with a neck between the shoulder and the working barrel; the bore of the retainer being of less diameter than that of the working barrel, and a ductile metal collar mounted on the neck and having annular beads that are normally spaced apart and that when installed are swaged into place to conform to the seat working barrel, so that more or less flexiblev adjustment of the working barrel relative to the plunger of the pump in said working barrel will occur during the pumping operation, thus relieving the pump of friction that might otherwise occur.

5. In a pump comprising tubing anda working barrel, a working barrel extension connected to the upper end of the workingl barrel, a neck connected to the working-barrel extension, a ring of ductile metal on said neck, means to retain said ring on the neck and a seat connected to the pump tubing to support said ring whereby the working barrel is suspended in a manner to allow it to adjust itself slightly to perfect the alinement of the working barrel with the tubing.

6. ln a pump having a working barrel and tubing,vthe combination with a tubing and working barrel of a taper seat connected to the tubing, a neck connected to the working barrel and located a distance above the upper end thereof, a ductile metal ring on the neck, means to hold the ring on the neck, said ring being seated in the taper seat, thereby suspending the working barrel from a distance above the same, said working barrel being otherwise free, whereby the working barrel is allowed to adjust itself slightly to perfect alinement with the tubing.

In testimony whereof, we have hereunto set our hands at Bakersfield, California, this 1st day of June, 1915.
